UNITED STATES TOM J. SCOTT, F

HEATER FOR Application filed November To all whom t may concern:

Be it known that I, TOM J. Soorr, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State o' Ohio, have invented certain new and useful Improvements in Heaters for Automobiles, of which the following is a specification.

It is the object of my invention to provide a new and improved heater of substantial construction for automobiles and so arranged that the escape of fumes into the inside of the automobile is precluded; to provide an interior arrangement for the heating element whereby the same acts as a cushion for the combustion-discharge to avoid percussive noise in the interior of the automobile; to provide novel means whereby the device may be applied to exhaust-pipes of various diameters; to provide novel means whereby the operation may be had from either side of the exhaust-pipe; and to provide novel adjustable clamping means for attaching the device to automobiles.

My invention is applicable to touring cars, roadsters and closed cars, as well as trucks and tractors, and other vehicles driven by internal combustion engines, and may be applied at any suitable point or points in the floor of the automobile. I have shown the same applied at the ootspace in liront of the rear seat of a touring car, it being assumed that the ear is supplied with a proper top and side and rear curtains, not shown because well-known.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Fig. 1 is a side elevation or" an automobile, partly broken away, showing my improved device applied thereto.

Fig. 2 is a plan view of my improved de- VICE.

Fig. 12 is a vertical axial section of a portion of the exhaust pipe and its valve; and

Fig. 13 is a horizontal axial section of the same.

21 represents the usual exhaust-pipe of the automobile, and 22 is the muiiler. An opening 23 is provided in this exhaust-pipe. 24 is a pivoted valve, arranged to normally close this opening. The valve is pivoted oii a stem 25 journaled in bearing-holes 26 located in the respective sides 27 of a clamp 28.

This clamp is formed of two matin sides struck up out of sheet-metal. Eac side comprises an arcuate apron-side 31, a wallsection 32 ofa passage 33, a web 34 connecting said wall-section and apron-side, and a fiange 35 above said wall-section. The wall-sections are at an angle to the arcuate sides. The portion of the side above the apron-side forms a rigid structure by reason of the manner in which the sheet-metal is formed, while flexure of the apron-side is permitted to change its arc of curvature to correspond to exhaust-pipes of different diameters.

The passage 33 communicates by means of the valve 24 with the opening 23 in the exhaust-pipe. A communicating pipe, shown as a flexible pipe 38, connects with the passage 33 and is arranged to be secured to the walls of said passage by means of a Cotter-pin 39. The fiexible pipe 38 communicates with the heating element 40.

The valve-stem has an extended shank 43. An operating arm is fixed to the extended shank and is normally retracted to close the valve by means of a spring 46. An operating link 47 connects with the operating arm. This operating link is of a flexible comparatively stii wire and operates lon itudinally in a vflexible guide 48, made for instance of 7 wouw *ru o, gliele toi? the operating -y A@ne end of the guide is secured to e has `rel e9, which is fixed to the usual in inenthos.rd 50 of the outoinobile. .ein operi sting shonl 5l is axially noveble in this loerrel hy ineens oi s handle 52. rThe eed of the :flexible link; is secured to this sho-ii "Ehe sh is axially inovehle to moi@ oi less extent to determine the degiee of openoi the vulve 2e, und is arranged to he secured adjusted positions hy slightly turning the shank in order to place o. pin iii the lozurrel selectively in notches in the outer fuse of the Well oi the sho/nk, to regulate the amount ot heet in the auto mobile. The ilexilole guide i8 may et s suituhle point he secured to the exhaustpijoe hy ineens ot a. clip 55.

rl'he elem-o 28 is arranged to he secured to exhaust-pipes of ditieient dis-meters. Ditierent outoniohiles have exhaust-pipes of' different diameters, so that this device may he spplied to different hinds ot automobiles., two sides oit' the cls-iup are eironged to he secured togetl'ier by means oi holte 57. 58, 59, At the pivot end of the clump there s lolooh @i which forms o separat block between the rear ends of the @lump-sections. is located between the Webs 34.- ond is part of the wall of the psssoge 83. The holt 59 is received through this hloeli und clumps the bloeit. and the resi' ends of the olen'ip-seotions together.

My improved device prevents fumes from reacl'iingr the interior of the vehicle; distributes the heat throughout the area of the cover section of the heating element, whence it is distributed throughout the interior of the vehicle; causes the impulses produced by the exhaust and received in the heating element to be cushioned by passing through the restricted space 94.- at the uppei.I edgeso the walls 87, 88, 8E), causing the heating element to act as a mutller, and permitting the exhaust to pass from the receiving manifold and passages to the exhaust passages and manifold and through the outlet-port- 93 of restricted area.

The cover section is imperforate to prevent communication between the interior of' the vehicle and the heating space in the heating element, and to prevent the lodgmcnt of dirt and moisture in the heating element and consequent deleterious fumes therefrom in the vehicle. The cover section is also preferably made of a material which .is light and strong and which readily 'transmits heat` -for instance ot a high-grade aluminum. The flexible communicating; pipe permits connection with the heating element placed in any suitable position,

I do not herein claire thn valve mechanism and means for securing the same, herein shown and described, having shown, described and claimed the saine in an application for Letters Patent et the United Stai Yes on improvements in valves for exhaust pipes ot automobiles, Serial No. 792,784@ tiled March 29, 192s, which is a division of this application.
